I don't envy your predicament. However that being said, I've always been a firm believer in the "peace of mind" route. Even though you say you like the watch, but the fact that you went through all the effort to get it inspected for shows that you expect nothing less than 100% authentic Rolex.

I would look for another watch, preferably with box + papers so that you'll have the "peace of mind". To me, that's priceless. Best of luck!
